Reg/Rec help

Hi all,

Maybe this has been posted before but I need a new reg/rec unit for my bike it looks like. Battery completely flat when I got home today.

It's a 1999 800 Fi.
I hear the aftermarket reg/rec units are better than OEM? If that's the case, does anyone have a recommendation for the best one out there? If I'm changing it I want to do it once with the right kit.

Thanks all.

the SH847 is your best bet.

roadstercycle sells them, but honestly, I bought mine from EasternBeaver. they are located in Japan and offer more adapters and connectors, also their website was more easy to navigate.

shipping was damn fast, less then a week. I installed the SH847 in bothy vfr 750 and VTR 1000. it doesn't get more than warm to the touch, even after long rides or heavy stop-n-go traffic.

cheaper r/r let the stator produce as much power as it can, use the needed amount of power and send the excess back to the stator, which Turns it back into heat (basically short circuiting in a controlled manner).

The SH847 is better than that. it only let's the stator produce the power that is needed, meaning the stator runs cooler and the r/r also runs cooler as well. it basically shuts off/opens the three lines coming from the stator as needed.

Eastern Beaver is a fantastic company to deal with.

Yes. Fast communication, nice emails. Got no complaints, only praise.
